GMDSS(the Global Maritime Distress and Safety System), which is utilizing recently developed systems such as satellite communications and positioning system, digital communication system, computer and microelectronics technology, etc., has been adopted by International Maritime Orgnization(IMO) and coordina-ted with such organization as the International Telecommunication Union(ITU), World Meteorological Organizatoion(WMO), etc. This system took effect partly on February 1st 1992 according to the 1988 SOLAS Amemdments and, after some more complementary measures, will be fully operational by February 1st 1999. Comparing with the existing communication system, the new system is mainly based on the latest scientific technologies, and therefore overall countermeasure will be necessary to accept the system reasonably. GMDSS will transform the current communication system basically and be the major factor to change the demand and supply of personnel for radio communication. To cope with the system assertively, regulations relating to the radio installation, the posting of radio operators, the bounds of their duty, etc. must be established and the demand and supply of radio operators to meet the system must be accomplished pertinently. Moreover, the technique and quality of the person-nel responsible for the system must be upgraded to carry out the obligations by international regulations as well as to ensure the safety of life and property at sea. Looking into the actual situations of our country, every regulation relating to the GMDSS has been improved, but the concerned educational institutions and administrations have not yet prepared the rational and concrete schemes on the educational methods and adquate procedures for the system. Therefore, in this thesis, the author intends to propose directions for improving the courses and contents of education of the relating educational institutions and to suggest rational schemes for balancing the demand and supply of personnel to the administrative anthorty concerned.

In recent years, the central ministries and regional self are competitively developing program for creating a trail and theme path by the increase of the number of trekkers. Even though these projects are developed in rural areas, it has been pointed out that most of projects do not directly linked to the revitalization of rural villages and improvement of non-farm income because of the main road itself as a resource in rural area. Therefore, in this study, we try to connect the citizen and the agriculture and rural area through the development of the green road which is the experience road with rural resource. To achieve this, we investigated the status and characteristics of the 36 villages where are the village was promoted various major project of first step. In second step, we considered the distinct characteristics of the area with conference of expert and site investigation for the final selection of 15 villages. Through two rounds' expert group consulting with checking, related literatures review and similar case-projects benchmarking, a riverside green road which is linked long distance trail and adjacent to the riverside was developed 15 courses by 2-development types proposed.

The purpose of this study was to investigate the knowledge level about ADHD in 207 of J and W universities special education students in Gyeonggi and Jeolla provinces. Data were gathered by using a survey method. To analyze data, statistical methods such as ANOVA and t-test were used. The results show the highest rate of correct answers in 'progress and treatment of ADHD' and the lowest rate of 'knowledge in the cause of ADHD'. The level of knowledge about ADHD is found to be different among the groups according to grade, major, experience with ADHD children and experience of taking related ADHD courses. On the other hand, the level of knowledge about ADHD don't differ according to gender and educational practice. Based on the results of this study, we discuss the necessity of acquiring knowledge about ADHD for pre-service special teachers and how to improve their teaching program for ADHD children.

Digital media has evolved in different areas as a result of the development of media and communications technology. The development of such media has also affected design in general as well as the design process systems focused on computer systems. Specifically, study of digital media design is based on a variety media and the development of computers due to social and environmental changes. Additionally, study is required on the convergence of variety of research including business, computer science, and human ergonomics. Nevertheless, most curricula in domestic universities are biased towards training practical manpower rather than creative/analytical manpower. For this reason, interchange between and study in multidisciplinary courses is desirable. Therefore, this study analyzes the curricula of departments of multimedia design of major universities and suggests enhanced curricula based on an analysis of the current state and understanding of the problem.

Ischemic and traumatic brain injuries are the major acute central nervous system disorders that need to be adequately diagnosed and treated. To find biomarkers for these acute brain injuries, plasma levels of some specialized pro-resolving mediators (SPMs, i.e., lipoxin A4 [LXA4], resolvin [Rv] E1, RvE2, RvD1 and RvD2), CD59 and interleukin (IL)-6 were measured at 0, 6, 24, 72, and 168 h after global cerebral ischemic (GCI) and traumatic brain injuries (TBI) in rats. Plasma LXA4 levels tended to increase at 24 and 72 h after GCI. Plasma RvE1, RvE2, RvD1, and RvD2 levels showed a biphasic response to GCI; a significant decrease at 6 h with a return to the levels of the sham group at 24 h, and again a decrease at 72 h. Plasma CD59 levels increased at 6 and 24 h post-GCI, and returned to basal levels at 72 h post-GCI. For TBI, plasma LXA4 levels tended to decrease, while RvE1, RvE2, RvD1, and RvD2 showed barely significant changes. Plasma IL-6 levels were significantly increased after GCI and TBI, but with different time courses. These results show that plasma LXA4, RvE1, RvE2, RvD1, RvD2, and CD59 levels display differential responses to GCI and TBI, and need to be evaluated for their usefulness as biomarkers.

Animation is breathing life into drawings through motion. Animation is formed by the afterimage phenomenon, that is, deviation of sequential pictures in every frame makes a person possibly perceive it as a live video. Consequently, animation is mostly produced using traditional frame-by-frame methods. The study of relations on timing has been a major concern of animation theory. Nevertheless, issues of timing on production outcomes and effectiveness are mostly ignored. Special focus, analysis and leadership studies on timing are addressed on animatics. Creating better timing through animatics, that is writing movies, directing, scheduling and amending storyboard in pre-production stage, eventually shorten time to animation production. This research is centered on animatics as a cutting edge educational courses. This course will introduce students to the animation production skill and instructors to in-depth teaching points. One of the concepts that we want to go for is keeping animatics apart from mere storyboard. In conjunction with the animation theory, this research conducted under the focus of production of animatics will lead to more efficient way of education on animatics.

Objective : Intrathecal methotrexate (MTX) therapy combined with whole brain radiotherapy (WBRT) is one of the major treatment modalities for leukemia and lymphoma involving the central nervous system (CNS). The purpose of this study was to retrospectively determine the incidences of leukoencephalopathy and disseminated necrotizing leukoencephalopathy (DNL) following intrathecal MTX therapy for CNS lymphoma or leukemia and to assess the potential risk factors. Methods : Between January 2000 and August 2009, 143 patients with CNS lymphoma or leukemia received intrathecal MTX therapy alone or in combination with WBRT at a single institution. Patients were followed up clinically and radiologically at regular two- or three-month intervals. Medical records were reviewed to obtain information regarding the patients' demographics, medical histories, radiologic characteristics, treatments, and clinical courses. Results : On follow-up MR images, leukoencephalopathy was found in 95 of 143 patients (66.4%). The median time to develop leukoencephalopathy was 6.6 months. Among those with leukoencephalopathy, four patients showed seven extensive white-matter changes with strongly enhancing lesions demonstrating DNL. Histological confirmation was done in six lesions of three patients and radiological diagnosis alone in one patient. Four lesions spontaneously disappeared on MR images without any treatment, with a mean duration of 14 months before disappearance of DNL. Conclusion : Leukoencephalopathy is a common phenomenon that occurs following intrathecal MTX therapy; however, DNL occurs at a very low incidence. For newly developed enhancing lesions, consideration for the occurrence of DNL should be taken to avoid unnecessary invasive procedures or therapies.
